    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 Q3I^(Ll"L  
    &e6!/y&  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: [0n[\& 0  
    enableservice('AutomationServer', true) |kGQ~:k+P  
    enableservice('AutomationServer') dLfB){>S  
    b]b+PK*h  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 &"?S0S>r!  
     &<LBz|  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: l86gs6>  
    1. 在FRED脚本编辑界面找到参考. bs&>QsI?j  
    2. 找到Matlab Automation Server Type Library !+u K@z&G  
    3. 将名字改为MLAPP 6]sP"

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 .%EYof

    3. 在探测面追迹光线 aD+4uGN  
    4. 在探测面计算照度 Yi j^hs@eV  
    5. 使用PutWorkspaceData发送照度数据到Matlab I.[Lv7U-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v`@NwH<r  
    7. 用Matlab画出照度数据 Sh2BU3
